A highly mutated variant of the Omicron strain, called BA.2.86, has raised concerns across the world as cases surge in the U.S., the U.K., China and several parts of Europe. Experts now believe the new variant, also dubbed Pirola, is less contagious and immune evasive than feared. In two separate lab experiments conducted in the

COVID-19 manifests differently from person to person. While most only develop mild sickness after catching SARS-CoV-2, others may require intensive care at hospitals to survive their bout with the virus. This stark difference has led scientists to turn their attention to genetics. After analyzing the DNA of more than 24,000 people who had COVID-19 and
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in the coronavirus disease 2019 (COVID-19) pandemic and has claimed more than 6.26 million lives. Households represent a high-risk exposure setting for SARS-CoV-2 transmission, and the role of children in spreading the virus is not known. A new study published in the
Pharmaceutical giant Pfizer shared promising results Thursday regarding its COVID-19 booster dose for children aged 5 to 11. The company said that an additional shot of its mRNA vaccine increased antibodies against Omicron by 36 times for the age group, based on data it conducted from a subset of its a 140-person study. The children participating in
Millions of people were lining up daily to get their shots. Instead of the steady drumbeat of cases, hospitalizations and deaths, we were tracking a new number: the percentage of Americans who had been vaccinated. This number, we believed, was our best chance to beat the virus. The US was caught up in a fever
If you’re relying on nasal or throat-based tests to give you a clean bill of health after a COVID-19 infection, you might be swabbing the wrong end. A study by researchers at Stanford Medicine has found that infected people can shed viral genetic material in their feces for up to seven months after diagnosis. Those who do often suffer
In a recent early release Pediatrics journal study, researchers investigate the presence of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children between the ages of five and 19 after infection.

COVID-19 has taken the world by surprise since 2020, affecting millions globally. Due to the uniqueness of the SARS-CoV-2 virus, the virus that causes COVID-19, scientists are following individuals who have been infected to better understand both the short- and long-term effects – particularly the cognitive effects of ‘Long COVID‘. An ongoing study from the
A study from Epic Research found that pregnancy, along with other comorbidities, can increase the chance of getting a breakthrough COVID-19 infection. A breakthrough COVID-19 infection is defined as a group of fully vaccinated individuals who are still susceptible to a COVID-19 infection if they are exposed to the virus. Authors of the study reviewed over 10 million medical records of patients
A study published Thursday in the medical journal JAMA Network Open found that the J&J vaccine remains durable and effective, even through the surge of cases caused by the Delta variant. It was 76% effective overall in preventing Covid-19 infections and 81% effective in preventing Covid-related hospitalizations. The study also showed that it provided lasting
Public health experts aren’t quite clear on what the future holds for Covid-19 vaccines — but some say it’s looking more and more like these shots could be needed on a yearly basis, similar to how flu shots are recommended each fall. “In order to keep it under control, we likely will need some form
A recent study posted to the bioRxiv* preprint server evaluated the effects of the waning of antibodies after coronavirus disease 2019 (COVID-19) infection or vaccination. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causal agent of the COVID-19 pandemic, has evolved throughout the pandemic into novel variants of concern. The risk of the emergence of new
A team of scientists from Australia has recently evaluated the impact of 112-day strict lockdown implemented in Melbourne, Australia, to control the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Interestingly, the study highlights that the lockdown has the highest negative impact on mothers with young children. The study is currently available on the
The World Health Organization (WHO) has warned against the negative effects and dangers of teleworking or working from home amid the ongoing COVID-19 pandemic. The public health agency also called for crucial changes to protect the overall health of employees engaging in distance working. Dangers Of Teleworking Although working from home has opened the doors
Canada’s COVID-19 vaccination rate is 76% — 10 times higher than it is across the continent of Africa. While people in the wealthy West have had preferred access to multiple rounds of vaccines, vast numbers of people, especially in Africa and on the Indian subcontinent, haven’t received a single dose. This has permitted the virus to
The mass lockdowns and restrictions imposed by governments to prevent the spread of coronavirus disease 2019 (COVID-19) were dominant throughout 2020 and 2021, and it was only the development and mass deployment of several vaccines that allowed these policies to be dismantled. Researchers from IQVIA Real-World Solutions have investigated how effective these vaccines are against
The COVID-19 pandemic has led to deficiencies and large inequalities in the care of mothers and newborns in Europe. This is shown by a study in which researchers from the University of Gothenburg and Lund University took part and are now presenting the results. The article, published in the scientific journal The Lancet Regional Health
Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Some Americans with a weakened immune system who face high risks for severe COVID-19 become eligible this week to receive a fourth dose of a coronavirus vaccine. The CDC endorsed a third dose of the Pfizer or Moderna vaccines for moderately
The omicron variant quickly took over the global coronavirus landscape after it was first reported in South Africa in late November, 2021. The U.S. became the 24th country to report a case of omicron infection when health officials announced on Dec. 1, 2021, that the new strain had been identified in a patient in California.
In a recent study published in the United States Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report, researchers determined the characteristics and clinical outcomes of coronavirus disease 2019 (COVID-19) in children and adolescents 18 years or younger.

In New York, some
Currently, the new Omicron or B.1.1.529 variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global cause of concern due to its ability to escape immunity and vaccine protection and cause coronavirus disease 2019 (COVID-19). A new study examines the variation in vaccine effectiveness against virus variants using estimated reductions in neutralizing
As winter begins and the holidays are in full swing, the COVID-19 pandemic has entered another worrying phase. Emergence of the omicron variant, along with increasing rates of infections, have left many people unsure about their holiday plans. On Dec. 2, 2021, President Joe Biden outlined a series of actions to respond to the COVID-19
Most severe acute respiratory syndrome coronavirus (SARS-CoV-2) mutations cause only mild harm. However, a small percentage of mutations can boost viral virulence and promote host-virus interactions that are critical to viral entry and infection. For example, SARS-CoV-2 spike protein mutations can significantly affect viral behavior, as the spike protein mediates viral attachment to host cell

A surprising new study published on the preprint server medRxiv* finds that following mild coronavirus disease 2019 (COVID-19), children are significantly more likely to remain seronegative than adults, irrespective of the viral load or symptom severity. This finding has implications for the serological diagnosis of COVID-19 in children, as well as for their immunity following
